the way he's submitting recordings using all sorts of old versions of MAME is also suspicious

that's not a 'normal' way of doing things, and IMHO still strongly indicates he's sourcing replays from more than one person and/or is aware of emulation bugs leading to subtle game exploits in certain versions.

On the pacgal-fast submission, I have played that one back successfully. I also have tested the DIP settings on wolfmame 0.78 to 0.101, and 0.106 and 0.193.

It appears that the DIP switch settings to allow for "Cheat speedup" on the menu is only available from 0.78 till 0.101. On 0.106 till the latest it is not available. I still have to test his "mspacman clone" submission which was played on a most recent version of wolfmame.

I have played back some of his other mspac* clone submissions and they all are fine. I think those "mspac* / pac* clone submission are legit but all the other games where TK2012 and PP are the same user are not.

why am i seeing both accounts again? I thought the point of moving all the scores so there would only be 1 account?

Because except me, you, and a very few other regular/historical MARPers, nobody here, expecially among the staff, seems to give a f**k anymore about MARP credibility....while everywhere else people work hard to expose cheaters, here they're tolerated, and therefore, encouraged....

It's so damn simple....rule 1.d) (At MARP, only ONE account is allowed per player; if two accounts have the same email or IP address, or anything proves to be created by the same player, only the first account will be kept.) even foresees what to do in case of infringment...so no doubts....no interpretations....just apply it....but nobody seems to have enough courage to do his job, and take the right decisions....
